Managing director of travel website Cheapflights.co.uk Andrew Shelton says there are fears about how Brexit will influence the cost of travelling to Europe.

He said: "Today's referendum will throw the spotlight onto many benefits British travellers have taken for granted for years.

"Chief among these will be the European open skies agreements which created the environment for the budget airlines to thrive and which may now have to be renegotiated; a robust UK currency that has made the Eurozone socheap to visit, the end of mobile data roaming charges, free healthcare within the EU and unlimited shopping allowances."

He added: "The UK travel market is vital to the economy of many European countries and regions. It will be in their interests to seek ways to maintain the status quo.

"We believe a lot of effort will be made in the coming months and years to ensure the UK cash cow isn’t put out to pasture."

As the pound plummeted to its lowest value since 1985 as news of the referendum result broke on Friday morning (June 24), those going on holiday this year find themselves facing paying more for foreign currency.

The Pound is down against every single major currency group, including the dollar and euro.

Sterling crashed 10% against the dollar during the night to 1.33 US dollars, a low not seen in 30 years.

Ironically, given that immigration was such a key issue in the referendum, Brits could now see more people travelling to the UK from overseas on holiday as the UK become a more affordable tourist destination.

The victory for the Leave campaign, though, is unlikely to have any immediate impact on UK tourists passing through immigration controls abroad, or for inbound tourism.

A spokesman for Heathrow Airport said: "Anyone travelling through the airport will find it operating normally with no changes to security and immigration."
